Articles like these always repeat it is hard to hire in the SV. I got a few interviews to do remote working for such startups and some of them said it was not possible to work with me only four days per week (I'd like a part time job). If talent is so rare, why is it better to go with zero hours instead of four days ? (Or maybe I just suck at something they don't want to say and telling me about the part-time requirement is easier.)
